Kernrechtsfrage
Whether mutual legal assistance was barred because the request concerned a fiscal offence rather than tax fraud.
Extrahierter Entscheid
The request described conduct amounting under Swiss law to tax fraud by arglist, so assistance could be granted.
Extrahierte Begründung
The court held that the decisive test is Swiss law. Submitting materially false balance sheets with the tax return constitutes deceptive use of documents and therefore tax fraud. The request set out sufficient facts to support the suspicion; there was no indication of a mere pretext to obtain otherwise unavailable evidence.
